Application filed September 10, 1906. Serial No. 333,985-

To all whom, it may concern.-

Be it known that I, HENRY M. ETTER, a citizen of the United States, residing at Shippensburg, in the county of Cumberland and State of Pennsylvania, have invented certain new and useful Improvements in Pumps, of which the following is a specification.

This invention contemplates certain new and useful improvements in pumps of that class that are intended to be operated by a windmill as well as by hand; and it relates particularly to the operating elements of the pump.

The object of my invention is to provide an improved construction and arrangement of the operating elements of a pump of this character which will permit the hand operating device to be expeditiously and con veniently detached from and engaged with the pump-rod, so that when the pump is being operated by the wind merely the handle may be swung free and not be oscillated up and down nor require the uncoupling of the handle proper from the hand-operated gear, while the invention also provides means for as readily coupling the hand-operated gear to the pump-rod whenever desired.

With this and other objects in view, as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements, and combinations of the parts hereinafter described, and more particularly pointed out in the appended claims.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation of the upper portion or head of a pump embodying the im provements of my invention, the upper por tion of the head being partially broken away to show the interior actuating parts. Fig. 2 is a horizontal sectional view, the section being taken approximately through the handoperated gear and its concomitant parts and showing such parts in the detached position. Fig. 3 is a rear elevation of the upper portion of the pump-head. Fig. 4 is a detail perspective view of the upper portion of one side or section of the pump-head looking at the interior thereof and showing one of the supporting-arms, of which there is a pair, that support the hand-operated gear or segments in position to be detached from and engaged with the rack-bar that is secured to the pumprod. Figs. 5, 6, and 7 are views substantially like Fig. 1, but with the parts shown in different positions.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawing, the numeral 1 designates a pump body or stock, which may be of any desired construction or design, and 2 designates the pump-head, which is supp orted up on the pump-body and which is preferably constructed in two mating halves or sections, each of which is preferably a casting of open or frame like formation embodying two vertically-extending standards 3. These standards are integrally connected together at their upper ends to form cheek-pieces 4, and said cheek-pieces are provided at their upper edges with inwardly-extending lips 5, producing a chamber 6 between the two cheek-pieces. These two similar castings or halves that together constitute the pump head are bolted together at their lower ends around the neck of the pump-body and are also bolted together at their upper ends, as by bolts 7 or similar fastening means.

8 designates the pump-rod, and 9 designates an actuating-rack which is secured in any desired manner at its lower end to the upper end of the pump-rod and which is arranged at its upper end for detachable connection to the operating rod or shaft of the windmill. (Not shown.) The upper extension of the pump-head is so shaped as to produce a bearing-surface 10 adjacent one face or edge of the rack 9 and arranged to serve as a guide-surface for one side of said rack, while the other edge or side of the rack is preferably guided by means of a roller 11, having its trunnions mounted within and between two bosses 12, which project inwardly into the chambers 6 from the inner walls of the cheek-pieces 4.

The hand-operated segment 13 is formed with an extension 14, in which the operatinghandle (not shown) is designed to be secured, and said segment is provided with two oppositely-extending trunnions 15, designed to be removably inserted and have bearing in sockets formed in bosses 16 on one end of two supporting-arms 17. The bosses 16 fit removably in pockets 16*, which are formed integrally in the cheek-pieces 4 and which extend horizontally and open outwardly, as

shown. The opposite ends of the supporting arms 17 are secured together by a bolt 18, and a spacing-sleeve 19 preferably encircles said bolt between the ends of said arms. The arms 17 are formed with two sets of oppositely-alined apertures 20 and 21, either set of which is designed to be brought into registry with corresponding apertures 22 in the cheek-pieces 4 of the pump-head, and

a pin 23 is intended to be inserted through the apertures 22 and through the coinciding apertures 20 and 2]., according as the arms 17 are moved inwardly or outwardly in the pump-head to hold said arms in either of these two positions, and consequently to hold the segment 13, which is supported by said arms, in engagement with the teeth of the rack-bar 9 or out of engagement with said. teeth. Hence it will be seen that the segment 13 may be disengaged from the rack whenever desired by moving the arms 17 forwardly to carry the bosses 16 outwardly in the pockets 16 while the movement of the arms in the opposite direction will cause the segment to be brought into meshing engagement with the teeth of the rack-bar. It is to be particularly noted that the bolt 18, which secures the arms 17 together at one end, is so arranged that its nuts will abut against the rear edges of the cheek-pieces 4 of the pump-head when the arms 17 are turned out far enough to allow the pin 23 to be inserted through the apertures 20 and 22. Hence this bolt will limit the outward move ment of the arms 17 and assist in the accurate the necessity of any especial care being taken by the operator.

As shown in the drawings, and particularly in Figs. 1, 3, 5, 6, and 7, the rack-bar 9 is provided with a lug 24. This lug is so positioned with respect to the rack-bar that it limits the downward movement of the rack by engagement with the upper surface of one of the lips 5 at the proper point for the engagement of the segment 13 with the teeth of the rack-bar. In the proper adjustment of the parts to engage the segments 13 with the raclcbar the handle portion 14 is raised to its upper limit before the arms 17 are pushed inwardly, and the parts are carried inwardly in this position. (See Fig. 6.) The lug 24 holds the rack-bar 9 then at such elevation that its smooth surface 9 above its teeth would strike the teeth of the segment 13 (see Fig. 5) and prevent the proper engagement of the two sets of teeth unless the segment 13 has been swung around to the position just before stated, as shown in Fig. 6. When in this position, the teeth of the segment will enter the teeth of the rack-bar and not be stopped by the solid surface 9 above the teeth, and consequently the two uppermost teeth of the segment and rackbar will engage with each other, and all the other teeth will follow in succession in proper mesh, whereas otherwise the two parts would not mesh properly and a full swing could not be given to the handle. It is also to be noted that the bosses 12, which are directly intended to receive the trunnions of the hand friction-roller 11, also perform the function of guides or sliding recesses for the ends of the supporting-arms 17 in their back-andforth movement to engage and disengage the gears,.said arms being preferably provided with flanges 17, sliding directly upon the upper surface of the said bosses 12. The opposite ends of the supporting-arms 17 are obviously guided in the pockets 16*, and thereby both ends of the arms 17 are preferably maintained in position when sliding back and forth, so that the apertures 20 or 21 will accurately register with the apertures 22 in the pump-head.

From the foregoing description, in connec tion with the accompanying drawings, it will be seen that Ihave provided a simple and durable arrangement of parts producing a detachable pump-gear which may be cheaply constructed and readily assembled. The proportion of the parts is such that the engagement by the bosses 16 of the rear walls of the pockets 16 will occur when the apertures 21 are in correct alinement with the apertures 22 of the pump-head for the reception of the pin 23, and, conversely, the bolt is so arranged that its nuts will engage with the rear edges of the cheek-pieces 4 when the arms 17 are moved in the opposite direction in order to aline the apertures 20 with the apertures 22. Hence no especial care need be taken by the operator in adjusting the parts in the engagement or disengagement of the gears.

In order to separate the parts of my detachable gear construction, it is only necessary to remove the bolt 18, whereupon both arms 17 may be withdrawn completely from the chamber 6 of the pump-head and the segment 13 may be readily removed from the two arms, as the trunnions 15 of said segment merely rest in a removable manner in the sockets of the bosses 16.

When the gears are detached one from the other, as illustrated best in Fig. 7, the handle that is connected to the extension 141 of the segment 13 will merely swing freely to the downward limit of its movement and there hang without having any movement imparted to it by the up-anrtdown reciprocation of the pump-rod.
